Project Overview The International Tundra Experiment (ITEX) network has collected data on phenology, plant growth, community composition, and ecosystem properties as part of a greater effort to study environmental Arctic change. The network has played a key role in advancing knowledge related to the likely impacts of a warmer Arctic through the use of experimentally … Continued

Project Overview GPS data continues to provide key clues to the Caribbean region’s geologic faults. GPS stations are currently being installed as part of the Continuously Operating Caribbean GPS Observational Network (COCONet), strengthening the indispensible collection of data belonging to a region that faces many atmospheric and geologic natural hazards. UNAVCO Connection With assistance from students … Continued

Project Overview Determining how the Caribbean plate moves with respect to the neighboring North America and South America plates has been a major challenge. Geologic plate motion models using seafloor magnetic anomaly rates, transform fault azimuths, and slip vectors are challenging due to sparse data. The only rates come from the Cayman Spreading Center, and … Continued

Project Overview The Continuously Operating Caribbean GPS Observational Network (COCONet) was recently expanded with the installation of a new GPS station on the island of Trinidad. This island is the lowest latitude landform of the West Indian island arc chain, and the new station now marks the most south easterly boundary of COCONet. However, two … Continued

Project Overview In 2006, while collecting samples of rock, Bucknell University researchers Craig Kochel and Rob Jacob discovered landforms in the Wrangell Mountains of Alaska that had previously been uncharacterized. These newly discovered landforms were named icy debris fans due to similarities with alluvial fans. An alluvial fan is a fan- or cone-shaped deposit of … Continued

Project Overview Puerto Rico and the northern Virgin Islands define the eastern terminus of the Greater Antilles, which extend eastward from offshore eastern Central America to the Lesser Antilles volcanic arc and mark the boundary between the Caribbean and North America plates. In Hispaniola, Puerto Rico, and the northern Virgin Islands, the Puerto Rico trench … Continued

Project Overview UNAVCO staff installed 3 new COCONet continuous GPS/MET sites in Panama, which complement the previously installed CN33 (ca. November 2011) continuous GPS/MET site. A total of 4 new COCONet cGPS and meteorological sites (CN20, CN28, CN33, and CN34) are now operational in Panama. In addition, COCONet is receiving continuous GPS data from four … Continued

Project Overview The Natural Resources Conservation Service stated that Colorado needed a wet March this year to get any real drought relief, noting that the March 1 snowpack measurement reflected a “nominal” increase in the month of February, but statewide snowpack remained at just 73 percent of average. In a statement, the agency stated that, … Continued

Project Overview The first continuous GNSS station on South Georgia Island was installed in February 2013 as a collaboration between the University of Luxembourg, the British National Oceanographic Centre, the British Antarctic Survey, and UNAVCO. Field Season The field team visited King Edward Point (KEP) research station for one week. GNSS station KEPA was built … Continued

Project Overview Two sites at the most southern part of the North American continental plate were installed in Mexico as part of the ongoing Continuously Operating Caribbean GPS Observational Network (COCONet). COCONet is funded by the National Science Foundation with the aim of developing a large-scale geodetic and atmospheric infrastructure in the Caribbean that will form … Continued

Project Overview The Toutle River is a 17.2-mile (27.7 km) tributary of the Cowlitz River in the U.S. state of Washington. It rises in two forks merging near Toutle below Mount St. Helens and joins the Cowlitz near Castle Rock, 20 miles (32 km) upstream of the larger river’s confluence with the Columbia River. The … Continued
